Selecting Slide

Projection Lenses

When buying a lens, consider features such as focal length (measured in

millimetres), aperture (designed as an f/stop), and the lens design (curved or

ﬂat).

When selecting a lens, remember that the shorter the focal length (i.e., the

smaller the f/number), the brighter the projected image. Also, a curved-ﬁeld

lens, in combination with cardboard open face mounts from an automated

mounting process, provide superior projection quality. A ﬂat-ﬁeld lens is the

best choice for glass-mounted slides.
